The role of accretion efficiency, natal kicks, and angular momentum transport in the formation of the Gaia black holes
Michela Mapelli, Cecilia Sgalletta, Johanna Müller-Horn +5
Gaia has the potential to deliver several tens of new dormant black holes (BHs) with low-mass stellar companions (hereafter, Gaia BHs) in the upcoming fourth data release. Three Ga…

Population synthesis of Be X-ray binaries in the Small Magellanic Cloud: Angular momentum recycling and stable mass transfer
VÃctor López Oller, Víctor López Oller, Boyuan Liu +6
Be X-ray binaries (BeXRBs) are key laboratories to constrain binary interaction processes such as mass transfer, angular-momentum transport, and natal kicks. The Small Magellanic C…

The boring history of Gaia BH3 from isolated binary evolution
Giuliano Iorio, Stefano Torniamenti, Michela Mapelli +15
Gaia BH3 is the first observed dormant black hole (BH) with a mass of M and represents the first confirmation that such massive BHs are associated with metal-…
